Detailed Description

The embodiments are described in detail below with reference to the drawings. However, the detailed description above may be omitted. For example, detailed descriptions of already known matters or repetitive descriptions of substantially the same configuration may be omitted.

The drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

As shown in fig. 1, the tank-retractable oral cavity cleaning device 1 of the present embodiment includes a tank 3, a device main body 5, and a nozzle 7.

The tank 3 is formed in a bottomed cylindrical shape. The tank 3 is internally provided with a storage section 9 for storing a liquid such as water (hereinafter referred to as water). The apparatus main body 5 is supported by the storage section 9 so as to be slidable in the longitudinal direction (hereinafter, referred to as the height direction). When the tank-telescopic oral cavity cleaning device 1 is not used, the device main body 5 is housed in the storage section 9. When the tank-telescopic oral cavity cleaning device 1 is used, the device main body 5 is pulled out from the storage section 9. In this case, water is supplied to the reservoir 9 of the tank 3.

The apparatus main body 5 is formed in a cylindrical shape with both ends closed in the height direction. The apparatus main body 5 is provided with a pipe 11, and the pipe 11 is disposed in the reservoir 9 of the tank 3. A filter (not shown) for removing foreign matters mixed in the water stored in the storage unit 9 is provided at the 1 st end of the pipe 11. The 2 nd end of the tube 11 communicates with a suction passage 13 provided inside the apparatus main body 5. The suction path 13 communicates with a pump 15 built in the apparatus main body 5, and supplies water in the tank 3 sucked up by the pipe 11 by driving the pump 15 to the pump 15.

The pump 15 includes a motor 17, a cam 19, a piston 21, and a pump chamber 23. The motor 17 is driven by supplying electric power from a rechargeable battery (not shown) housed inside the apparatus main body 5. The cam 19 converts the rotation of the motor 17 into an axial operation force. The piston 21 reciprocates in the height direction of the apparatus main body 5 by the operation force in the axial direction converted by the cam 19. The end of the piston 21 is disposed in the pump chamber 23, and the volume of the pump chamber 23 is changed by the reciprocating motion of the piston 21. The pump chamber 23 communicates with a suction path 13 and a discharge path 25 provided in the apparatus main body 5, respectively. Further, a suction valve (not shown) is provided between the pump chamber 23 and the suction path 13, and a discharge valve (not shown) is provided between the pump chamber 23 and the discharge path 25.

When the piston 21 is moved in a direction to increase the volume of the pump chamber 23 by the driving of the motor 17, the pump 15 causes the water in the tank 3 to flow into the pump chamber 23 through the pipe 11 and the suction passage 13. When the piston 21 is moved in a direction to reduce the volume of the pump chamber 23 by the driving of the motor 17, the water flowing into the pump chamber 23 is discharged to the nozzle 7 through the discharge passage 25.

The nozzle 7 is formed in a hollow elongated shape and is detachable from the apparatus main body 5. The nozzle 7 communicates with the ejection passage 25 in its inside in a state of being attached to the apparatus main body 5. The nozzle 7 ejects water flowing out of the ejection path 25 from the tip.

When the oral cavity cleaning device 1 of the telescopic tank type is not in use, the nozzle 7 is detached from the device main body 5, and the device main body 5 is pushed into the tank 3 and stored in the tank 3. In use of the tank-retractable oral cavity cleaning device 1, the device body 5 is pulled out from the tank 3, and the nozzle 7 is attached to the device body 5. The details of the tank-retractable oral cavity cleaning device 1 will be described below with reference to fig. 1 to 23.

As shown in fig. 1 to 12, the apparatus main body 5 is formed in a cylindrical shape with both ends closed in the height direction. The cross-sectional shape of the device body 5 is formed into a perfect circle so as to be relatively rotatable with respect to the tank 3. As shown in fig. 2, 3, 11, and 12, a nozzle mounting portion 27 is provided on the upper surface of the apparatus main body 5, in which the nozzle 7 is detachably disposed. The end of the nozzle 7 is inserted into the nozzle mounting portion 27, and an engaging portion (not shown) provided inside the nozzle mounting portion 27 is engaged with an engaged portion (not shown) of the end of the nozzle 7, thereby maintaining the mounted state of the nozzle 7. The nozzle 7 attached to the nozzle attachment portion 27 can be detached from the apparatus main body 5 by releasing the engagement between the engagement portion and the engaged portion by pressing a button 29 (see fig. 12) provided above the side surface of the apparatus main body 5.

As shown in fig. 2 and 11, a power switch 31 for starting or stopping the tank-retractable oral cavity cleaning device 1 is provided on the side surface of the device main body 5. An intensity selection switch 33 is provided below the power switch 31 on the side surface of the apparatus main body 5, and the intensity selection switch 33 is used to switch the output of the motor 17 of the pump 15 and the ejection intensity of the water ejected from the nozzle 7. A display lamp 35 is provided below the intensity selection switch 33 on the side surface of the apparatus main body 5, and the display lamp 35 displays the on/off state of the power switch 31, the selection intensity of the intensity selection switch 33, and the like. As shown in fig. 12, a cover 37 is provided on the side surface of the device main body 5 at a position circumferentially different from the indicator lamp 35 and above the indicator lamp 35, and the cover 37 protects a charging connector of a rechargeable battery incorporated in the device main body 5.

As shown in fig. 1, 4, 11, and 12, a tube 11 communicating with a suction passage 13 is integrally attached to the lower surface of the apparatus main body 5. The tube 11 has a length to the extent that the tube reaches the bottom of the tank 3 in a state where the apparatus main body 5 is pulled out from the tank 3 (see fig. 2). In a state where the apparatus main body 5 is housed in the tank 3, the tube 11 is housed in the tank 3 in a state of being wound a plurality of times. A coil spring 39 is disposed around the pipe 11, and the coil spring 39 maintains a posture extending in the longitudinal direction of the pipe 11. By disposing the coil spring 39, the tube 11 can be wound without being bent when the apparatus main body 5 is stored in the tank 3, and the tube 11 can be stored in the tank 3 in order. Further, by disposing the coil spring 39, the tube 11 can be extended neatly from the wound state when the apparatus main body 5 is pulled out from the tank 3.

As shown in fig. 10 and 12, a nozzle housing 41 is provided on a side surface of the apparatus main body 5. The nozzle housing 41 is formed in a groove shape capable of housing the nozzle 7, and extends in the height direction of the apparatus main body 5. The nozzle 7 detached from the apparatus main body 5 is housed in the nozzle housing portion 41. By providing the nozzle housing 41 in the apparatus main body 5, the nozzle 7 detached from the apparatus main body 5 can be handled together with the apparatus main body 5. Therefore, it is not necessary to manage the nozzle 7 detached from the apparatus main body 5 separately from the apparatus main body 5, and the management of the nozzle 7 can be easily performed.

As shown in fig. 11 and 12, a pull-out projection 43 projecting from the side surface of the apparatus main body 5 is provided below the side surface of the apparatus main body 5. The pull-out projection 43 projects along the circumferential direction of the apparatus body 5. A plurality of (here, two) pull-out projections 43 are provided in the circumferential direction on the side surface of the apparatus main body 5. The pull-out projection 43 constitutes a holding portion 45, and the holding portion 45 holds the device body 5 to the can 3 when the device body 5 is pulled out from the can 3.

A storage projection 47 projecting from the side surface of the apparatus main body 5 is provided below the pull-out projection 43 on the side surface of the apparatus main body 5. The receiving projection 47 projects along the circumferential direction of the apparatus main body 5. A plurality of (here, two) housing projections 47 are provided in the circumferential direction on the side surface of the apparatus main body 5. The housing projection 47 constitutes a locking portion 49, and the locking portion 49 holds the device body 5 to the tank 3 when the device body 5 is housed in the tank 3.

As shown in fig. 12, a mark projection 51 projecting from the side surface of the apparatus main body 5 is provided above the side surface of the apparatus main body 5. The mark projection 51 constitutes a mark portion 53, and the mark portion 53 serves as a reference for positioning the lock portion 49 when the apparatus main body 5 is stored in the tank 3.

As shown in fig. 11 and 12, a lower gasket 55 as a sealing member is attached to the lower side of the apparatus main body 5 by being in close contact with a groove continuously formed in the circumferential direction on the outer circumferential surface of the apparatus main body 5. In a state where the device body 5 is attached to the tank 3, the outer peripheral surface of the lower gasket 55 is in close contact with the inner peripheral surface of the tank 3, thereby sealing the device body 5 and the tank 3. The lower pad 55 is detachably attached to the groove of the apparatus main body 5, and only the lower pad 55 can be cleaned by detaching the lower pad 55 from the apparatus main body 5.

Such a device main body 5 is slidably supported by the tank 3. As shown in fig. 2, when the tank-retractable oral cavity cleaning device 1 is used, the device body 5 is pulled out from the tank 3. On the other hand, as shown in fig. 3, when the tank-telescopic oral cavity cleaning apparatus 1 is not used, the apparatus main body 5 is housed in the tank 3.

The tank 3 is formed of, for example, polypropylene resin or the like so as to be washable with a dishwasher, and is made transparent or translucent to improve design. As shown in fig. 1 to 10 and 13 to 21, the tank 3 is formed in a bottomed tubular shape having one end side open in the height direction and the other end side closed. The sectional shape of the tank 3 is a perfect circle so that the apparatus body 5 can be relatively rotated. The interior of the tank 3 serves as a reservoir 9 for storing water. The apparatus main body 5 is supported by the storage section 9 so as to be slidable in the height direction. The reservoir 9 can house a portion of the apparatus main body 5 other than the upper surface side. As representatively shown in fig. 13 and 14, the can 3 includes a cylindrical body 57 and a bottom wall 59.

The cylindrical body 57 constitutes the circumferential wall of the tank 3 and most of the reservoir 9. As shown in fig. 15, a mounting projection 61 projecting from the inner peripheral surface of the cylindrical body 57 is provided below the inner peripheral surface of the cylindrical body 57. The mounting projection 61 projects along the circumferential direction of the cylindrical body 57. An engagement recess 63 is provided on an outer surface of the mounting projection 61. A plurality of (two in this case) mounting projections 61 are provided on the inner circumferential surface of the cylindrical body 57 in the circumferential direction. The lengths of the plurality of mounting

projections

61, 61 extending in the circumferential direction of the cylindrical body 57 are different from each other. The mounting projection 61 constitutes a mounting portion 65 that enables the bottom wall 59 to be attached to and detached from the tubular body 57.

As shown in fig. 16, the bottom wall 59 forms a bottom wall of the tank 3 that closes the lower opening of the cylindrical body 57, and forms the storage section 9 in a state of being attached to the cylindrical body 57. As shown in fig. 19 to 22, a peripheral wall 67 is provided on the outer peripheral side of the bottom wall 59, and the peripheral wall 67 protrudes from the bottom surface toward the cylindrical body 57 and is continuous in the circumferential direction. The height of the peripheral wall 67 is set to a height that allows the user's fingers to reach the bottom surface when the bottom wall 59 is removed from the cylindrical body 57. Further, since the can 3 is transparent, it is preferable to make the peripheral wall 67 as low as possible so that the boundary between the cylindrical body 57 and the bottom wall 59 is not conspicuous when the bottom wall 59 is attached to the cylindrical body 57.

As shown in fig. 15 and 19, a mounting recess 69 is provided on the outer surface of the peripheral wall 67 of the bottom wall 59. The mounting recess 69 is open upward, and one circumferential side of the peripheral wall 67 of the mounting recess 69 serves as a bottom into which the mounting projection 61 is inserted. An engaging projection 71 engageable with the engaging recess 63 of the mounting projection 61 is formed to project on the bottom side of the mounting recess 69. An inclined surface 73 inclined upward from the bottom toward the opening is provided between the opening and the bottom of the mounting recess 69. A plurality of (here, two) mounting recesses 69 are provided in the circumferential direction of the outer peripheral surface of the peripheral wall 67. The opening lengths of the openings of the plurality of mounting

recesses

69, 69 in the circumferential direction of the peripheral wall 67 are different from each other. The opening lengths of the openings of the plurality of mounting

recesses

69, 69 correspond to the projecting lengths of the plurality of mounting

projections

61, 61 in the circumferential direction, respectively, so that the plurality of mounting

projections

61, 61 can be inserted. The mounting recess 69 together with the mounting projection 61 of the tubular body 57 constitutes a mounting portion 65 that enables the bottom wall 59 to be attached to and detached from the tubular body 57.

When the bottom wall 59 is attached to the tubular body 57, first, the

attachment projections

61, 61 are disposed in the attachment portions 65 at the openings of the attachment recesses 69, 69. Next, the cylindrical body 57 and the bottom wall 59 are relatively moved in the direction of approaching in the height direction to insert the mounting

projections

61, 61 into the openings of the mounting recesses 69, 69. Then, in a state where the mounting

projections

61, 61 are inserted into the mounting recesses 69, the cylindrical body 57 and the bottom wall 59 are relatively rotated, and the mounting

projections

61, 61 are inserted into the bottoms of the mounting recesses 69, 69. At this time, the engagement recess 63 of the mounting projection 61 is engaged with the engagement projection 71 of the mounting recess 69, thereby maintaining the mounted state of the bottom wall 59 to the cylindrical body 57.

When the bottom wall 59 is detached from the tubular body 57, first, the tubular body 57 and the bottom wall 59 are relatively rotated, and the

attachment projections

61, 61 are pulled out from the bottom portions of the attachment recesses 69, 69 in the attachment portion 65. At this time, the engagement between the engagement recess 63 of the mounting projection 61 and the engagement projection 71 of the mounting recess 69 is released. Next, the cylindrical body 57 and the bottom wall 59 are continuously rotated relatively, the mounting

projections

61, 61 are brought into contact with the

inclined surfaces

73, 73 of the mounting recesses 69, and the cylindrical body 57 and the bottom wall 59 are further continuously rotated relatively. At this time, the mounting

projections

61, 61 slide with respect to the inclined surfaces 73, and the cylindrical body 57 and the bottom wall 59 are relatively moved in the direction away from each other in the height direction. The mounting

projections

61, 61 that have completed sliding with respect to the

inclined surfaces

73, 73 are disposed at the openings of the mounting recesses 69, 69. Then, the bottom wall 59 can be detached from the cylindrical body 57 by relatively moving the cylindrical body 57 and the bottom wall 59 in the direction of separation in the height direction.

The mounting portion 65 has a screw structure in which the mounting protrusion 61 and the mounting recess 69 are engaged with each other. Therefore, the bottom wall 59 can be attached to and detached from the cylindrical body 57 by rotating the bottom wall 59 around the axial center of the cylindrical body 57. In such a mounting portion 65, the plurality of mounting

projections

61, 61 are different in projection length in the circumferential direction from each other. Therefore, the mounting position of the bottom wall 59 to the cylindrical body 57 can be positioned at one location in the circumferential direction. Further, the attachment portion 65 is provided at one circumferential position, whereby the attachment position of the bottom wall 59 can be positioned, but since there is a possibility that the bottom wall 59 may largely move with respect to the tubular body 57, the attachment portion 65 is preferably provided at a plurality of circumferential positions.

Here, in the conventional can, the tubular body 57 and the bottom wall 59 are formed of one continuous member. Therefore, in the conventional tank, the bottom wall 59 cannot be detached from the cylindrical body 57, and when cleaning the inner surface of the tank, fingers do not reach the bottom surface from the opening of the tank, and a long brush for cleaning or the like is required.

In contrast, the tank 3 is constituted by a cylindrical body 57 having a bottom wall at least a part of which is openable, and a bottom wall 59 detachably attached to the cylindrical body 57. In such a tank 3, the bottom wall 59 is detached from the cylindrical body 57 when cleaning the inside of the tank 3. Since the bottom surface of the bottom wall 59 removed from the tubular body 57 can be obtained with fingers, it is not necessary to use a long cleaning brush or the like. Therefore, the inner bottom surface of the tank 3 can be easily cleaned. Further, since the peripheral wall 67 of the bottom wall 59 is set to a height at which fingers can reach the bottom surface, the inside of the tank 3 can be easily cleaned.

As shown in fig. 15, 16, and 19 to 21, a bottom gasket 75 as a sealing member is disposed between the cylindrical body 57 and the bottom wall 59. As shown in fig. 16, 20, and 21, the bottom gasket 75 is attached by being closely attached to a groove 77 continuously formed in the circumferential direction on the outer circumferential surface of the circumferential wall 67 of the bottom wall 59. The bottom pad 75 is detachable from the groove 77. A lip that can be brought into close contact with the inner peripheral surface of the cylindrical body 57 is continuously formed on the outer peripheral surface of the bottom gasket 75 in the circumferential direction. The bottom gasket 75 seals between the cylindrical body 57 and the bottom wall 59 by being in close contact with the cylindrical body 57 and the bottom wall 59. The groove 77 may be provided on the inner circumferential surface of the cylindrical body 57.

Here, in the conventional can, the sealing member such as the bottom gasket 75 is formed integrally with the can, and the sealing member cannot be removed without breaking a part of the can. Further, when the sealing member is disposed on the bottom wall side of the tank, cleaning of the sealing member is difficult, and dirt such as scale and mold is likely to adhere to the sealing member.

In contrast, the bottom pad 75 is detachably attached to the groove 77 of the bottom wall 59, and the bottom wall 59 is detachably attached to the tubular body 57. Therefore, when the bottom liner 75 is removed from the tank 3 at the time of cleaning or the like, the bottom wall 59 is removed from the tubular body 57, whereby the bottom liner 75 can be easily removed from the groove 77 of the bottom wall 59. Further, since the bottom liner 75 can be easily detached from the tank 3, the bottom liner 75 can be easily cleaned, and the bottom liner 75 can be maintained in a clean state.

As shown in fig. 15 and 19, a notch 79 is provided in a wall portion above the groove 77 in which the base gasket 75 is attached, and the notch 79 is formed so as to be spaced apart from the outer peripheral surface of the base gasket 75. By inserting the user's finger into the notch 79, the finger can be brought into contact with the outer peripheral surface of the base pad 75. Therefore, the bottom gasket 75 attached to the groove 77 can be easily detached from the groove 77. Further, a plurality of notches 79 may be provided in the circumferential direction of the groove 77.

Here, as a structure in which at least a part of the bottom wall of the tank 3 is openable, for example, the tank 3 may be configured by the cylindrical body 57 and the bottom wall 59, and a screw-type attachment portion 65 that is detachable may be provided between the cylindrical body 57 and the bottom wall 59. In this configuration, the bottom wall 59 can be attached to the cylindrical body 57 or detached from the cylindrical body 57 by relatively rotating the cylindrical body 57 and the bottom wall 59. In this configuration, since the cylindrical body 57 and the bottom wall 59 are relatively rotated, at least the screw-type mounting portion 65 needs to be formed of a cylinder. The following configuration may be adopted: composed of a cylindrical body 57 and the bottom wall 59 constitutes the can 3, the bottom wall 59 is openable and closable relative to the tubular body 57 by a mounting portion 65 formed by a hinge or the like, for example. The structure may be such that: the cylindrical body 57 and the bottom wall 59 constitute the tank 3, and the bottom wall 59 is detachably attached to the cylindrical body 57 via an attachment portion 65, which is constituted by a fitting portion or the like that is slidably fitted in the height direction or the right-left direction, for example.

As another configuration, for example, the can 3 is constituted by a single member in which the cylindrical body 57 and the bottom wall 59 are continuous, and an opening communicating with the bottom surface inside the bottom wall 59 is provided in the bottom wall 59, and a lid for closing the opening is provided. In this configuration, it is preferable that the opening of the bottom wall 59 is opened to allow a finger to be inserted to clean the entire bottom surface inside the bottom wall 59. The lid for closing the opening is preferably capable of keeping the opening closed, and is provided on the bottom wall 59 so as to be openable and closable by a hinge, provided with an engaging portion engageable with the bottom wall 59 at least at one location, or engageable with the bottom wall 59 as a whole, for example.

Here, in the conventional tank, the tubular body 57 and the bottom wall 59 are formed by a single continuous member, and at least a part of the bottom wall 59 is not opened, so that the water remaining in the tank cannot be discarded in a state where the apparatus main body 5 is attached to the tank. Therefore, in the conventional tank, when the water remaining in the tank is discarded, the apparatus main body 5 needs to be detached from the tank. Further, when the device body 5 is detached from the can, the water remaining in the tank may splash to the surroundings.

In contrast, the can 3 is formed so that at least a part of the bottom wall can be opened. Therefore, when water remaining in the tank 3 is discarded, the water can be discarded from the opening, and the apparatus main body 5 does not need to be detached from the tank 3. Further, since the water remaining in the tank 3 can be discarded without detaching the device body 5 from the tank 3, the water remaining in the tank 3 can be suppressed from splashing to the surroundings. Therefore, the burden of cleaning around the can-telescopic oral cavity cleaning device 1 after use can be reduced.

The apparatus main body 5 is supported by the tank 3 so as to be slidable in the height direction. As shown in fig. 2, 4, and 10, when the oral cavity cleaning device 1 of the telescopic tank type is used, the device main body 5 is pulled out from the tank 3. The apparatus main body 5 is held in a pulled-out state pulled out from the tank 3 by the holding portion 45. On the other hand, as representatively shown in fig. 3 and 6, when the use of the tank-retractable oral cavity cleaning device 1 is finished, the device body 5 is housed in the tank 3. The device body 5 is held in the housed state housed in the tank 3 by the lock portion 49.

As shown in fig. 4 and 5, the holding portion 45 includes the pull-out projection 43 of the apparatus main body 5 and a pull-out recess 81 provided in the can 3 and engageable with the pull-out projection 43. The pull-out recess 81 is also shown in fig. 16. The pull-out recess 81 is provided above the inner peripheral surface of the tubular body 57 of the tank 3 so as to be engageable with the pull-out projection 43 of the apparatus main body 5. The pullout recess 81 is formed continuously in the circumferential direction of the cylindrical body 57 so as to be engageable with the plurality of

pullout projections

43, 43.

When the device main body 5 is pulled out from the can 3, the pull-out projection 43 of the holding portion 45 engages with the pull-out recess 81, and the device main body 5 is held at the pull-out position with respect to the can 3. Further, by pulling out the device main body 5 from the pulled-out position of the can 3, the engagement of the holding portion 45 is released, and the device main body 5 can be detached from the can 3. In the holding portion 45, the pull-out projection 43 is provided at a position overlapping the tank 3 when viewed from the front in a state where the apparatus main body 5 is attached to the tank 3. Therefore, in a state where the apparatus main body 5 is attached to the tank 3, the pull-out projection 43 is not exposed from the tank 3 in a front view, and an excessive unevenness can be hidden, so that the appearance can be improved.

As shown in fig. 6 and 7, the lock portion 49 includes a housing projection 47 of the device body 5 and a housing recess 83 provided in the tank 3 and engageable with the housing projection 47. The housing recess 83 is also shown in fig. 20 and 21. The housing recess 83 is provided on the inner circumferential surface of the circumferential wall 67 of the bottom wall 59 of the tank 3 so as to be engageable with the housing projection 47 of the apparatus main body 5. The housing recess 83 protrudes along the circumferential direction of the peripheral wall 67. The extension length in the circumferential direction of the housing recess 83 is set longer than the extension length in the circumferential direction of the housing projection 47. A plurality of (two in this case) housing recesses 83 are provided on the inner circumferential surface of the circumferential wall 67 so as to be engageable with the plurality of

housing projections

47, 47.

Inclined surfaces

85, 85 inclined upward from below are provided on both sides of the housing recess 83 in the circumferential direction.

When the device main body 5 is stored in the tank 3, the storage protrusion 47 of the lock portion 49 engages with the storage recess 83, and the device main body 5 is held at the storage position with respect to the tank 3. In addition, although the tube 11 is not shown, the tube 11 is wound a plurality of times and is accommodated between the apparatus main body 5 and the tank 3. In addition to this, the present invention is, a lower packing 55 is disposed above the receiving projection 47. By disposing the lower packing 55 above the housing projection 47, the lower packing 55 does not interfere with the housing recess 83 when the apparatus main body 5 is housed in the tank 3 or when the apparatus main body 5 is pulled out from the tank 3, and wear of the lower packing 55 can be reduced.

Here, conventionally, when the device body 5 held by the lock portion 49 is pulled out from the tank 3, the device body 5 is gripped and pulled out from the tank 3, and the engagement of the lock portion 49 is released. However, for example, when water or the like adheres to the apparatus main body 5, the apparatus main body 5 slips and the apparatus main body 5 may not be pulled out from the tank 3. In such a case, it is difficult to release the engagement of the lock portion 49.

Therefore, as shown in fig. 20 and 21, inclined surfaces 85, 85 are provided on both sides of the circumferential direction of the peripheral wall 67 in the housing recess 83 of the lock portion 49, that is, on both sides in the relative rotation direction of the apparatus main body 5 and the tank 3. Therefore, by relatively rotating the apparatus main body 5 and the tank 3, the housing projection 47 is brought into contact with the inclined surface 85, and the housing projection 47 is slidably moved along the inclined surface 85. When the housing projection 47 moves along the inclined surface 85, the apparatus main body 5 moves upward to be pulled out from the can 3. When the apparatus main body 5 moves upward, the engagement between the storage protrusion 47 and the storage recess 83 is released in the lock portion 49. In a state where the engagement of the lock portion 49 is released, the apparatus main body 5 can be easily pulled out from the tank 3.

In such a lock 49, even when the device main body 5 slips, the engagement of the lock 49 can be easily released by relatively rotating the device main body 5 and the tank 3. Therefore, the apparatus main body 5 can be easily pulled out from the can 3. In a state where the engagement of the lock portion 49 is released, the housing projection 47 moves along the inclined surface 85, thereby moving the apparatus main body 5 in a direction of being pulled out from the tank 3. Therefore, the area of the gripping device body 5 is increased, and the device body 5 can be more easily pulled out from the tank 3.

Further, as a locking portion that can release engagement by relatively rotating the device main body 5 and the tank 3, for example, the

inclined surfaces

85, 85 may not be provided on both sides in the circumferential direction of the housing recess 83. In this case, the engagement of the lock portion is released by relatively rotating the device body 5 and the tank 3 to position the engagement projection 71 outside the range of the accommodation recess 83. Even with such a locking portion, the device body 5 can be easily pulled out from the tank 3.

The housing projection 47 constituting the locking portion 49 is provided on the side surface of the device main body 5 at a position overlapping the can 3 when the device main body 5 is pulled out from the can 3 in a front view. Therefore, as shown in fig. 2, in a state where the apparatus main body 5 is pulled out from the can 3, the housing projection 47 is not exposed from the can 3 in a front view, and an excessive unevenness can be hidden, so that the appearance can be improved.

Such a locking portion 49 is provided inside the tank 3, and even if the tank 3 is formed to be transparent, it is difficult to observe engagement or disengagement. Therefore, as shown in fig. 8 and 9, a mark portion 53 serving as a reference for the engagement state of the lock portion 49 is provided at a portion visible from the outside of the tank 3.

As shown in fig. 8 and 9, the marking portion 53 includes a marking protrusion 51 of the apparatus main body 5 and a marking recess 87 provided in the tank 3 and engageable with the marking protrusion 51. The mark recess 87 is provided at an opening edge above the cylindrical body 57 of the tank 3 so as to be engageable with the mark projection 51. The portion of the mark recess 87 that engages with the mark projection 51 is defined as a bottom portion, and

inclined surfaces

89, 89 inclined upward are provided from the bottom portion to both sides in the circumferential direction.

Such a marking portion 53 indicates that the housing projection 47 and the housing recess 83 engage in the lock portion 49 when the marking projection 51 of the apparatus main body 5 engages with the bottom of the marking recess 87 of the tank 3. Therefore, the user can recognize that the lock portion 49 is engaged by visually checking the engagement of the marker projection 51 and the marker recess 87.

When the apparatus main body 5 and the tank 3 are relatively rotated, the mark projection 51 of the mark portion 53 slidably moves along the inclined surface 89. When the marker projection 51 moves along the inclined surface 89, the apparatus main body 5 moves upward to be pulled out from the can 3. Therefore, the engagement release of the lock portion 49 can be assisted. When the movement of the index projection 51 on the inclined surface 89 is completed, as shown in fig. 9, the index projection 51 is disposed on the opening edge of the cylindrical body 57, and it is known that the engagement between the housing projection 47 and the housing recess 83 is released in the lock portion 49. Therefore, the user can recognize that the engagement of the lock portion 49 is released by visually confirming that the engagement of the mark projection 51 and the mark recess 87 is released.

Here, as shown in fig. 8 to 10, a drying hole 91 penetrating the peripheral wall of the cylindrical body 57 is provided above the side surface of the cylindrical body 57 of the tank 3. In a state where the apparatus main body 5 is housed in the tank 3, the drying hole 91 is disposed to face the nozzle housing portion 41 of the apparatus main body 5. By providing the drying hole 91 in the tank 3 in this manner, the nozzle 7 housed in the nozzle housing portion 41 can be dried. Further, in a state where the apparatus main body 5 is pulled out from the tank 3, the drying hole 91 is disposed to face the bottom wall side of the nozzle housing portion 41 of the apparatus main body 5. By disposing the drying hole 91 in this manner, the water accumulated in the nozzle housing 41 can be discharged from the drying hole 91.

In the telescopic tank type oral cavity cleaning device 1, since the tank 3 is constituted by the tubular body 57 and the detachable bottom wall 59, the bottom wall 59 can be detached to supply water to the reservoir 9 in the tank 3. However, when water is added to a washbasin or the like, there is no problem if the water supply port is of a type that can be extended, such as a shower head type, but in the case of a water supply port of a type that cannot be extended, it may be difficult to supply water by raising the tank 3 from which the bottom wall 59 is removed. Therefore, it is preferable that water can be supplied to the reservoir 9 in the tank 3 even in a state where the tank 3 is placed upside down.

Therefore, as shown in fig. 16 to 18, a liquid supply hole 93 for injecting water into the reservoir 9 is formed in a side surface of the tank 3. As shown in fig. 16 and 18, the liquid supply hole 93 is formed in a cylindrical shape protruding from the side surface of the tank 3. The liquid supply hole 93 is disposed such that the liquid supply hole 93 is positioned below the lower liner 55 in a state where the apparatus main body 5 is pulled out from the tank 3. The liquid supply hole 93 is disposed such that the liquid supply hole 93 is positioned above the lower gasket 55 in a state where the apparatus main body 5 is housed in the tank 3. By disposing the liquid supply hole 93 in this manner, the liquid supply hole 93 does not interfere with the lower packing 55, and the sealing performance of the lower packing 55 can be maintained. As shown in fig. 8 to 10, the liquid supply hole 93 is closed by a liquid supply cover 95.

As shown in fig. 22 and 23, the liquid supply cap 95 is provided with a closing portion 97, and the closing portion 97 has an outer diameter larger than that of the liquid supply hole 93. The outline of the closing portion 97 is formed as a racetrack ellipse in which both sides in the vertical direction are formed by curved surfaces and both sides in the horizontal direction are formed straightly. The outer surface of the closing portion 97 is curved along the side shape of the can 3. By forming the closing portion 97 in this way, the appearance can be improved. A peripheral wall 99 is formed continuously in the circumferential direction on the inner surface of the closing portion 97, and the peripheral wall 99 projects toward the liquid supply hole 93 and is insertable into the inner periphery of the liquid supply hole 93. As shown in fig. 16 to 18, the liquid supply lid 95 is attached to the tank 3 via a hinge 101 so as to be openable and closable in the vertical direction. The liquid supply lid 95 may be provided so as to be openable and closable in the left-right direction with respect to the tank 3 via a hinge 101, for example, and the opening and closing direction of the liquid supply lid 95 may be any direction.

As shown in fig. 16 and 18, the hinge 101 is composed of a shaft 103 provided on the can 3 and a hook 105 provided on the liquid supply lid 95, and the hook 105 is rotatably engaged with the shaft 103. The hook 105 is also shown in fig. 22 and 23. The liquid supply lid 95 is detachable from the tank 3 by constituting the hinge 101 with the shaft 103 and the hook 105. Therefore, only the liquid supply cover 95 can be cleaned. Further, the hinge 101 may be formed by providing the hook 105 on the tank 3 and the shaft 103 on the liquid supply lid 95. The hinge may be formed continuously with the tank 3 and the liquid supply lid 95.

As shown in fig. 16 to 18, the hinge 101 is provided at a position where the whole is shielded by the closing portion 97 of the liquid supply lid 95 in a front view. By covering the hinge 101 with the liquid supply lid 95, the hinge 101 can be protected, and damage to the hinge 101 can be suppressed. Further, the hook 105 is not provided at the end of the liquid supply cover 95, and the strength of the hook 105 can be increased to improve the strength of the hinge 101. Alternatively, at least a part of the hinge 101 may be hidden by the liquid supply cover 95 when viewed from the front. In addition, in the case where the hinge 101 has a high strength, the hinge 101 may not be covered by the liquid supply cover 95. The hinge 101 is disposed at such a position: when the user holds the bottom wall 59 and attaches and detaches the bottom wall 59 to and from the cylindrical body 57, the user's fingers do not touch the hinge 101. By disposing the hinge 101 in this manner, the bottom wall 59 can be easily attached to and detached from the cylindrical body 57 without interfering with the hinge 101.

As shown in fig. 16 and 18, a liquid supply gasket 107 as a sealing member is disposed between the liquid supply hole 93 and the liquid supply cap 95. As shown in fig. 22, the liquid supply packing 107 is attached by being closely attached to a groove 109 continuously formed in the circumferential direction on the outer circumferential surface of the circumferential wall 99 of the liquid supply cover 95. The liquid supply gasket 107 is removable from the tank 109. In a state where the liquid supply hole 93 is closed by the liquid supply cover 95, the outer peripheral surface of the liquid supply gasket 107 is in close contact with the inner peripheral surface of the liquid supply hole 93. The liquid supply gasket 107 seals between the liquid supply hole 93 and the liquid supply cover 95 by being in close contact with the liquid supply hole 93 and the liquid supply cover 95. The groove 109 may be provided on the inner circumferential surface of the liquid supply hole 93.

A notch 111 is provided in a wall portion above the groove 109 to which the liquid supply pad 107 is attached, and the notch 111 is formed by being spaced apart from the outer peripheral surface of the liquid supply pad 107. A plurality of (here, two) notches 111 are provided in the circumferential direction of the groove 109. The notch 111 may be provided at one location in the circumferential direction of the groove 109. By inserting the user's finger into the notch 111, the finger can be brought into contact with the outer peripheral surface of the liquid supply pad 107. Therefore, the liquid supply gasket 107 attached to the groove 109 can be easily detached from the groove 109.

Here, conventionally, when the liquid supply lid 95 is opened with respect to the liquid supply hole 93, an end portion of the liquid supply lid 95 protrudes from a side surface of the tank 3 in a front view. Therefore, when the liquid supply lid 95 is opened, for example, if the can 3 falls, the protruding end of the liquid supply lid 95 collides with peripheral members, and the hinge 101 holding the liquid supply lid 95 may be broken.

Therefore, as shown in fig. 17 and 18, the end of the liquid supply cover 95 is disposed in a range of the side surface of the tank 3 when viewed from the front in a state where the liquid supply cover 95 is opened. Specifically, the end of the liquid supply lid 95 on the opposite side of the hinge 101 is disposed at a position not protruding from the lower end of the side surface of the can 3 when viewed from the front in the state where the liquid supply lid 95 is opened. Therefore, the interference between the end of the liquid supply cover 95 and peripheral members can be suppressed when the liquid supply cover 95 is opened, and the influence on the hinge 101 can be suppressed.

In such a tank-telescopic oral cavity cleaning device 1, a lock portion 49 for holding the device body 5 to the tank 3 in a stored state is formed between the device body 5 and the tank 3. Further, the device main body 5 is rotated relative to the tank 3, whereby the device main body 5 is released from being held by the lock portion 49 relative to the tank 3. Therefore, by rotating the device main body 5 relative to the tank 3, the device main body 5 can be pulled out from the tank 3 in a state where the holding of the device main body 5 relative to the tank 3 by the lock portion 49 is released.

Therefore, in such a tank-retractable oral cavity cleaning device 1, the device body 5 can be easily pulled out from the tank 3.

When the device main body 5 is rotated relative to the tank 3 to release the holding of the device main body 5 relative to the tank 3 by the lock portion 49, the device main body 5 moves in a direction of being pulled out from the tank 3. Therefore, the device main body 5 can be more easily pulled out from the tank 3 while achieving a reduction in size when the device main body 5 is stored in the tank 3. Further, when the holding of the device main body 5 with respect to the tank 3 by the lock portion 49 is released, the amount of projection of the device main body 5 from the tank 3 increases, the device main body 5 is easily gripped, and the device main body 5 can be more easily pulled out from the tank 3.

Further, the lock portion 49 overlaps with the can 3 in a front view in a pulled-out state. Therefore, when the device main body 5 is pulled out from the tank 3, the lock portion 49 is not exposed, and the appearance can be improved.

Further, since the above-described embodiments are intended to exemplify the technology of the present disclosure, various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims and their equivalents.
